What is Zero Trust Network Access (ZTNA)

Zero trust has been around for more than 10 years. But, as users work from anywhere, and apps move from inside the data center to outside the network perimeter, network and security teams have had to shift their focus. It’s no longer about securing a network. It’s about protecting users, devices, and business resources.

Execution of this framework combines advanced technologies such as risk based multi-factor authentication, identity protection, next-generation endpoint security, and robust cloud workload technology to verify a user or systems identity, consideration of access at that moment in time, and the maintenance of system security. Zero Trust also requires consideration of encryption of data, securing email, and verifying the hygiene of assets and endpoints before they connect to applications.

Verify Identity

Instead of trusting an IP address, establish the identity of the user and device using an identity provider (IDP) first

Set Contextual Policies

Define access policies based on user, device posture, location, and apps, and rely on a cloud service to enforce them

Improve Visibility and Adapt

Use logs to determine which users are accessing which apps, and auto-adapt based on any changes in context

Grant app access not network access

Connect workers to a specific app without the need for a VPN or network connection

Reduce the attack surface

Reduce attack surface by masking private apps from the internet, making them invisible to all except those expressly authorized to access

Enhance the user experience

Automatically deliver an optimal user experience, with fast, local connections regardless of user location

Support the bulk of devices and apps

Today 45% of companies allow the use of BYOD devices. Keep access secure to legacy and web-based apps regardless of device type
